The invention provides a gradient wave-transparent heat shield forming method. The gradient wave-transparent heat shield forming method comprises the steps that S1, a prefabricated body of a heat shield is prepared; s2, preparing ceramic slurry; s3, the ceramic slurry is blended into the prefabricated body of the heat shield to form a biscuit of the heat shield; s4, putting the biscuit of the heat shield into the ceramic slurry to densify the biscuit of the heat shield; and S5, sealing a large port of the biscuit of the heat shield, and infiltrating the biscuit of the heat shield by using polytetrafluoroethylene to form the heat shield. The heat shield prepared by the method not only has bearing and wave-transparent functions, but also has excellent heat insulation and heat protection functions. 本发明提供一种梯度透波隔热罩成型方法，包括：S1、制备隔热罩的预制体；S2、配置陶瓷浆料；S3、将陶瓷浆料融入隔热罩的预制体中形成隔热罩的素坯；S4、将隔热罩的素坯放入陶瓷浆料中，使得隔热罩的素坯致密化；S5、密封隔热罩的素坯的大端口，利用聚四氟乙烯对隔热罩的素坯进行溶渗形成隔热罩。该方法制备的防热罩不仅具有承载、透波功能，还具有优异的隔热和防热功能。
